The Shures have a problem with the cable housing material. It gets stiff and cracks within 3 to 6 months. The SE530s have a nice fit. They're overall, the best sounding earbuds I've tried.
The UEs housing will crack or detach due to pressure. Like when you take a nap while listening to music. The UEs also have a larger opening, so if you have smaller ear canals or use those extended silicone ear fittings, they will constantly push out of your ears reducing the seal and sound quality. IMO, the TripleFi.10 have a nicer high end than the SE530s, but lack a little bass.
If you want to try the UEs for cheap,
These Altec Lansings for $33 are just rebranded UE SuperFi.3 which are $102. These, like other UE products are lacking on the lower end.
Definitely read the reviews on the higher end earbuds and if you purchase a nice pair, use them sparingly and with care.
